4. The solenoid of claim 1 , wherein the member of the upper stator member has an annular groove, a part of the wire receiving portion of the half bobbin being received in the groove.

5. The solenoid of claim 1 , wherein an outer periphery of the member of the upper stator member is generally flush with an outer periphery of the portion of the half bobbin.

6. The solenoid of claim 1 , wherein the lower stator member has a portion that includes an outer tapered surface and an internal, generally cylindrical surface that define a tip, the tip being generally adjacent to the armature.

7. The solenoid of claim 6 , wherein the armature has an inner tapered surface such that when the armature moves towards the lower stator member, the inner tapered surface is generally adjacent to the outer tapered surface of the lower stator member.

8. The solenoid of claim 1 , wherein the upper stator member includes an opening therein, the armature being disposed in the opening.

9. The solenoid of claim 8 , wherein the armature has a generally cylindrical periphery, the solenoid further comprising a sleeve in the opening between the upper stator member and the armature, the sleeve having a generally cylindrical inner surface adjacent to the periphery of the armature.

10. The solenoid of claim 1 , further comprising a plastic material molded over the winding and at least a portion of the half bobbin.

11. An active control mount of an engine of a vehicle, the mount comprising:

a body, and

a solenoid mounted within the body, the solenoid comprising:

a shell,

a lower stator member associated with the shell,

an upper stator member in the shell, the upper stator member being separate from the lower stator member, the upper stator member having a wire receiving member,

a half bobbin associated with the upper stator member and separate there-from, the half bobbin having a wire receiving portion,

wire wound directly about the portion of the half bobbin and directly about the member of the upper stator member to define a winding, and

an armature magnetically attractable to at least the lower stator member upon energizing the winding.

12. The mount of claim 11 , wherein the member of the upper stator member is generally cylindrical and the upper stator member includes a generally cylindrical base coupled with the member, the base having a diameter larger than a diameter of the member.

13. The mount of claim 12 , wherein the portion of the half bobbin is generally cylindrical and the half bobbin has a generally cylindrical base member coupled with the portion, the base member having a diameter greater than the diameter of the portion, the winding being disposed between the base member of the half bobbin and the base of the upper stator member.

14. The mount of claim 11 , wherein the member of the upper stator member has an annular groove, a part of the wire receiving portion of the half bobbin being received in the groove.

15. The mount of claim 11 , wherein an outer periphery of the member of the upper stator member is generally flush with an outer periphery of the portion of the half bobbin.

16. The mount of claim 11 , wherein the lower stator member has a portion that includes an outer tapered surface and an internal, generally cylindrical surface that define a tip, the tip being generally adjacent to the armature.

17. The mount of claim 16 , wherein the armature has an inner tapered surface such that when the armature moves towards the lower stator member, the inner tapered surface is generally adjacent to the outer tapered surface of the lower stator member.

18. A method of providing a solenoid, the method comprising the steps of:

providing:

an upper stator member;

a lower stator member separate from the upper stator member, the upper stator member having a wire receiving member;

a half bobbin associated with the upper stator member and separate there-from, the half bobbin having a wire receiving portion; and

an armature, and

winding wire directly about the portion of the half bobbin and directly about the member of the upper stator member to define a winding,

wherein the armature is constructed and arranged to be magnetically attracted to at least one of the upper or lower stator members upon energizing the winding.

19. The method of claim 18 , wherein the step of providing the upper stator and the half bobbin includes providing an outer periphery of the member of the upper stator member to be generally flush with an outer periphery of the portion of the half bobbin.

20. The method of claim 19 , wherein the member and the portion are each generally cylindrical.
